ARCADIA, Calif., June 24 /PRNewswire/ -- Myricom (www.myri.com) announced
today at the International Supercomputer Conference in Heidelberg a new series
of Myrinet switches with up to 1280 fiber ports in a 14U rackmount enclosure.
These switches are based on a new, 32-port, Myrinet crossbar-switch chip,
which is also slated for use in other Myricom Myrinet-switch products and in
OEM blade systems.
These new products specifically address the growing market for clusters in
the range from hundreds to thousands of host computers. They reduce the cost
of the switch network, and simplify the installation and operation of large
Myrinet clusters are used for computationally demanding scientific and
engineering applications, and for data-intensive web and database
applications. There are many thousands of Myrinet clusters in use in more
than 50 countries, including several systems with more than 2000 processors.
Myrinet technology is used in 37.4% of the June-2004 TOP500 sites.
This line-card-based series of switches has many configurations. A
standalone 256-host full-bisection Clos network has a list price of only
$312 per host port, and will simplify and reduce the cost of the installation
of Myrinet clusters of this size.
A configuration with 256 host ports and 256 interswitch ports is one of
the building blocks for switch networks for clusters with 512, 768, 1024,
1280, and all the way up to 8192 hosts. Two of the "256 up, 256 down"
switches can be connected together for 512 hosts. At larger sizes, the
"256 up, 256 down" units connect to spine switches with up to 1280 ports each.
A special feature of these large configurations, which are full-bisection Clos
networks, is that all interswitch connections use quad-fiber ribbon cables,
thus simplifying installation.
The high port density of these switches is achieved by using fiber rather
than copper cables. Myrinet-2000 fiber links operate at a data rate of 2+2
Gigabits per second on multimode fiber up to 200m.
This series of Myrinet switches have a full complement of enterprise
features. The 14U rackmount enclosure uses front-to-back air flow, with
separate air paths for the four hot-swappable N+1 redundant power supplies and
for the line cards. The line-card cooling uses two series pairs of hot-
swappable blowers with N+2 redundancy. All line cards are also hot-swappable.
Switch monitoring is provided via dual-redundant 10/100 ethernet ports and
a built-in color TFT display. An internal network of microcontrollers reports
to a Linux-based microprocessor information that includes the status of all
ports, packet counts, packet errors, internal voltages, currents,
temperatures, and blower speeds.
Myricom, Inc., a privately held California Corporation founded in 1994,
created Myrinet, the leading high-speed network for connecting computers to
form clusters. In addition to direct sales, Myricom supplies Myrinet products
and software to IBM, HP, Dell, NEC, Sun, Linux Networx, Cray, and many other
OEM and system-integration companies.
